One of the difficult thing was not knowing during the whole porting process if in the end it would really work, or not... I almost gave up several time :)

I used to develop an emulator. Different scope, but I guess there are a lot of similarities, so I feel your pain.

Getting things working on platforms other than originally intended is really hard. Nice work!

How long did it take to port?

First commits on the repos (D3 and Regal) are from 17/12. I started to work on this a week or so before the first commits, so it took roughly 4 weeks, with daily progress and commits. In the end the amount of changes in the code is relatively small. Time was mostly spent investigating and figuring out WHAT changes needed to be done for things to work

Impressive man!

Can you talk a bit about the biggest problems you faced?

Also, I'm a bit familiar with the doom 3 code, and the loading a 400mb pk4 file issue can easily be fixed by extracting it and loading/streaming the necessary stuff for each level and such.

I am preparing a Readme file with more explanations. Yes I think I think I'll extract everything on the server, and implement some form of lazy loading thanks to some emscripten mechanism
